To all whom it may concern.- 7

Be it known that I, RICHARD THORN BECK- ETT, of Woodbury, Gloucester county, State of New Jersey, have invented a new and useful Improvement in Bottle-Forming Machines, (for which I have obtained a patent in Great Britain,No.1,687,bearingdate March 11, 1893; in France, No. 227,525, hearing date April 26, 1893,and in Belgium, No. 103,197, hearing date February 15, 1893,) of which the following is a specification. e

I will describe a bottle-forming machine, embodying my invention and then point out the novel features in claims.

In the accompanying drawings, Figure 1 is a front viewof a bottle-formingmachin'eembodying my invention. Fig. 2 is a side view thereof. Fig. 3 is a front view showing certain parts in a different position from that shown in Fig. 1. Fig. 4 is a side view thereof. Fig. 5 is an enlarged sectional detail showin g a modification. Fig. 6 is an enlarged plan view of acertain part. Fig. 7 is an enlarged sectional detail of a certain part. Fig. 8 isa plan and elevation of formers employed.

Referring by letter to the drawingsA designates a standard extending from a suitable base A.

A shows aswinging standard pivotally connected at its lower end to bearings ct extended upward from the base A. The swinging standard A carries the two part mold A Each part of the mold A at its lower end has a hinge or pivotal connection with a stud-a" on a plate or platform a, here shown as ad j ustably connected, by means of screws a to a plate a on the upper end of the swinging standard A By means of the screws a the plate a and the mold A may be adjusted vertically. Each part of the mold A is connected by an adjustable link a with a lever A shown as pivoted at one end to an arm a on the plate or platform a. The levers A at the opposite end, are pivotally connected by means of a bar a to the upwardly extending arms a of a brace bar A The brace bar A at its lower end extends through a slot opening in a plate 0, extended from the base A, and the bar is notched at its lower end to form shoulders a adapted to rest on the upper surface of the plate a", to hold the mold in operative position, as shown in Figs. 3 and 4.

To prevent the standard A from swinging too far forward a stop bolt A is employed. This bolt has a pivotal connection with the standard A andis extended through a sleeve 01, which is movable through a hole in the front wall of the standarcLA. The sleeve 0; has at each end an annular flange larger than the opening through the standard anda spring a interposed between the end of the sleeve to and a nut e on the stop bolt A serves as a cushion to prevent jar when the standard A? is moved to its forward position.

A is a vertically m ovable'rod provided with a plate or platform a at its upper end and having hearings in arms 01, projecting rearward from the standard A These bearings are so arranged relatively to the standard A that the rod A will assume a vertical position when the standard A is in its forward position as shown in Fig. 2. The lower end of the rod A is connected bya link a to a fulcrumed treadle A which at its forward portion has a spring a extended from it to the standard A which serves to return the rod A to its downwardpositioh.

B is the former for the bottom of a bottle adapted to engage inand form the bottom of the mold A and to have a slight vertical movement imparted to it by the mold sections asthey come together. The bottom former "B has on its lower side a stem 1) movable in a socket formed in a lug b'- on the plate or platform a Abevel or cam surface b is formed on the lower side of the bottomformer adapted to engage with corresponding bevels or cam I surfaces b in the lower portions of the mold sections. Obviously, when the mold sections are forced together the bevel'or cam surfaces b 6 will force the bottom former upward and depressthe bottom of the bulb of glass in the mold.

I will now describe the means for carrying a bulb of glass to the mold and expanding or blowing the same.

B designates a carrier here shown in the form of awheel mounted on a tubular hub B having a horizontal bearing B in the upper portion of the standard A. A pipe B provided with a valve 1), connects with the tubular hub B and serves to convey air, under pressure, to the interior of the hub for the purpose of blowing a bottle as will hereinafter appear.

0 designates a tubular casing, the interior of which forms an air chamber having communication with the tubular hub B The casing O is arranged at right angles to the hub B It has at one end a cap or stu'lfing box 0, and at the other end a cap or stuffing box 0 which, as here shown, has an annular groove 0 formed in it.

C is a blow tube having bearingsin the caps or stuffing boxes 0 C and movable 1ongitudinally of the casing O. The blow tube has a stem portion 0 extended through the stuffing box O and provided with a head 0 at its end. A spring surrounds the stem between the head 0 and the cap or stuffing box C and serves to move the blow tube longitudinally to bring its end 0 wholly within the cap or stuffing box 0 The blow tube is intended to be forced into the glass forming the neck of a bottle X and it is movable through asleeve F the projecting end of which is tapered to provide a former for the outwardly flaring mouth of the bottle. The chamber in the casing G communicates with the interior of the tube 0 through perforations 0 below a stop collar or sleeve 0 surrounding the tube 0 at one side of an annular shoulder 0 formed in the interior of the casing G. This shoulder and stop collar or sleeve prevents the spring 0 from moving the tube too far outward.

D designates tongs or formers for the exterior of the mouth of a bottle. The tongs or formers D are carried by the carrier B on arms D. The arms D have interior heads d to fit in the annular groove 0 of the cap or stufling box 0 The former sections D have a horizontal movement toward and from each other. An arm D extends rearward from each tong or former section D and the arms at the rear ends are pivoted on a bolt or stud d on a bracket D secured to the carrier B. Each section of the former D is removably secured to its arm D by means of a suitable thumb screw. The former sections are forced together by means of springs d hearing at one end against the arms D and at the other end against lugs projecting from the bracket D \Vhen desired, I employ a cam (i engaging the inner sides of forwardly projecting portions (1 of the arms D. The cam consists of a plate mounted on ashaft cl, having a bearingin a plate (1 secured to the cap piece 0 A handle 11" is provided for turning the cam plate. The former sections D hold the glass in position, before the mold A is placed around it, by means of inwardly projecting beads or shoulders 61 which forms the lower portion of the head of the bottle.

E shows a holder or receiver for glass. It is made in two separable sections adapted to fit closely together, similar to a mold A Each sect-ion is secured to an arm e. The

arms 6 are crossed and fulcrumed at their point of crossing to a stud 8 extended from the carrier 13. Links 6 are pivoted at one end to the ends of the crossed arms e at e, and at the opposite end these links 6 have a coincident pivotal connection with an operating lever E. The lever E has a pivotal connection a with the carrier B, and a yielding friction plate e is aifixed to the carrier B to engage with the lever E and hold it as adjusted. Obviously, by moving the lever E from one end to the other of the plate a the links and arms may be operated to close or separate the parts of the holder E as desired. It will be observed that the arms, links and lever first described are in the rear of the easing 0, and that the ends of the arms 6, connecting with the sections of the holder E are extended forward so as to bring the holder sections in line with the casing C. When the sections of the holder E are closed together they engage around a portion 6 of the tongs or formers D. The carrier B is intended to be oscillated back and forth, a one half revolution, and I therefore provide stops. These stops consist of a lug 6 extended rearward from the carrier, and lugs 6 extended from the standard A. \Vhen the lug 6 contacts with one of the lugs a a further movement is prevented. Set screws a may be provided on the lugs 6 for the purpose of adjustment.

In Fig. 5, I have shown a sleeve F, surrou uding the blow tube and within which the tube is movable longitudinally. This sleeve has at its end a former for forming the mouth of a bottle. The sleeve has opposite slotsf in its wall and a pin f extended through the blow tube projects into those slots. An annular shonlderf on the blow tube normally at some distance from the end of the sleeve allows the end of the blow tube to be forced some distance into the mass of glass before the shoulder f comes in contact with the end of the sleeve to force the end of the sleeve into the mouth portion of the bottle. When the blow tube is allowed to resume its normal position the pin f engaging with the end walls of the slots will draw the mouth former out of the glass, into which a small amount of air is admitted before the parts are reversed.

In operation the machine is placed in the position shown in Figs. 1 and 2, with the formers D closed and the receiver E also closed. After placing the glass in the receiver E, the blow tube is forced upward, by means of the treadle A the rod A and the link a, to push the mouth former into the mass of glass. Then the rod A is allowed to lower, and a small amount of air is admitted. Then the carrier is given a one-half rotation in the direction indicated by the arrow in Fig. 1, which will bring the parts thereon to a reverse position. Now the lever E is operated to separate the receiver sections as shown in Fig. 3. By drawing upward on the bar a standard A is caused to assume a vertical position and this motion causes the mold sections A to close around the glass. The several parts of the machine will now be in the position shown in Figs. 3 and 4. While the parts are in this position the valve 5 is opened to allow a pressure of air to enter and expand or blow the glass in the mold and form the bottle. After forming the bottle the mold A is removed and also the formers D and then the bottle is removed.
